HIS STUDY was done to evaluate adding different levels of Azolla to the diet of Japanese quail, and study its effects on the carcass traits, and some serum blood characteristics.The experiment was carried out in the poultry farm of the animal production department/college of agriculture/ Kirkuk university from (18 th Feb to 18 th April, 2022).Twenty male and sixty females at age 40 days were randomly allocated to five treatments (0% , 4% , 8% azolla, 4% azolla + Enzyme, and 8% azolla + Enzyme), each treatment consist of four replications that contain 1 male and 3 females.The birds were kept in a battery system with ad libitum water and diet.At the end of the experimental period, five birds (1 male: 4 female) were randomly taken from each treatment; the birds were weighed by using digital scale (0.01 g), and slaughtered to complete bleeding, followed by plucking the feather and then reweighed.The main, and the secondary parts were all record.And the blood was taken to exam the level of some serum blood characteristics (total protein, Glucose, cholesterol, albumin, globulin, and uric acid).Our result indicates that adding Azolla for 4% increase the body weight and carcass weight significantly comparing with the other treatments.Moreover, adding the Azolla with enzyme enhance the parts weight compare with other treatments.Also, all the serum blood traits were affected significantly by adding azolla powder.
